I've just published a blog post about my first Arduino project: a bar graph made of LEDs controlled by a light sensor.I know it's nothing extremely fancy or original, but I needed something to start, so please bear with me

Even if it's a quite simple project, I tried to show and share as much as possible, so it comes with pictures, the sketch code and a video.

Thanks for posting this. I am going to use it in a demonstration to some kids who are interested in Arduino. I think it is a great way to show them how a sensor can be used and a nice way to display the sensory input.
